‘Wonder Material’ Phosphorene Nanoribbons Live Up to Hype in First Demonstration

Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorous, which, similar to graphene, are made of single-atom-thick layers of atoms. PNRs were first…
